F17 SSMIS L1C Data Product Update

Due to continuing, intermittent anomalies in the F17 SSMIS 37v channel, starting from April 13, 2016 (Orbit # 48713 : 18:29:36) and forward all 1C F17 products will flag the 37V channel as bad data and the Brightness Temperatures will be missing.

We apologize for any inconvenience or problems that this may cause and appreciate your understanding and patience.
Please let us know if you have any questions or concerns.

Level 1C (L1C) algorithms are a collection of algorithms that produce common calibrated brightness temperature products for the Global Precipitation Measurement (GPM) Core and Constellation satellites.

This document describes the GPM Level 1C algorithms. It consists of physical and mathematical bases for orbitization, satellite intercalibration, and quality control, as well as the software architecture and implementation for the Level 1C algorithms.
